Abstract

Abstract:
Transmission line and light mono-poles are susceptible to structural vibration resulting from wind loads. Vibration mitigation and strengthening of steel poles have been studied. More recently a composite steel-concrete monopole was developed to support higher loads while having smaller ground line dimensions. The pole features a thin-walled hollow steel tube partially filled with concrete near the base to provide stability to the thin-walled tube. However, the dynamic properties of the newly developed poles were never investigated. Also, no attempts were made to investigate the optimal amount of concrete filling, to enhance the response of the poles when subjected to dynamic wind loads. In this paper, a finite element-based analysis was conducted to calculate the natural frequencies and mode shapes of conventional hollow steel poles. Results were verified using available numerical and experimental data. The method was then employed to calculate the natural frequencies and mode shapes of steel poles partly filled with concrete. A parametric study of the effect of the concrete filling length was also performed and utilized to find the optimal length of concrete filling. The new optimized composite pole features natural frequencies higher than the inherited frequencies of typical wind loads to better control wind-induced vibrations.
